In the 5th Aliyah of Parshas Toldos, we learn about the setup and ruse of Yaakov Avinu preparing to get the brachos instead of Eisav. Yaakov Avinu represents the inner world, and Yitzchak thought that Eisav should get the brachos, which are connected to the material world. However, Rivka understood that Eisav cannot have any power, and that his outer display of kibbud av (honoring his father) did not accurately reflect his rotten inner core. As children of Yaakov Avinu, we need to remember that the inside is what is important, focusing on real values and truth, even while in this material world.
